Amoeba staining is the process used in laboratories for observing the structural details of free-living and intestinal amoebae. It is needed because most amoebae are transparent in fresh samples, and their internal parts cannot be seen clearly without color contrast. It is the process that helps in identifying pathogenic forms like Entamoeba histolytica from non-pathogenic
A light microscope may be used to see and examine the vacuole’s structure. While the vacuole doesn’t stain as the other organelles of the cell (because it does not contain many constituents that stain) tests have demonstrated that staining is possible for this organelle because the vacuole’s sap absorbs and stores dyes that are colored.
Masson’s Trichrome Staining (MTS) is a special histological staining method used to differentiate the connective tissue elements of a section. Principle of the Masson’s Trichrome Staining The principle of Masson’s Trichrome Staining is based on the differential penetration of dyes into tissue components of different density, and it is the process where electrostatic attraction and
Positive staining of viruses covers the principle, reagents, TEM-grid and thin-section procedures, results, interpretation, advantages, limitations, and uses.
Auramine-rhodamine staining is used in microbiology laboratories for the examination of specimens suspected of containing acid-fast bacilli (AFB). The specimens are stained, differentiated and examined under a fluorescence microscope. Auramine stain is also used for the fluorescent examination of AFB. Auramine-rhodamine staining is used to examine sputum smears from patients suspected of pulmonary tuberculosis (TB).
